Severe apicomplexan infection in the oyster Ostrea chilensis: a possible predisposing factor in bonamiosis [PDF]

Diseases of Aquatic Organisms, 2002
Histological examination of 6455 oysters Ostrea chilensis from Foveaux Strait south of New Zealand over a 5 yr period showed >85% contained apicomplexan zoites, irrespective of season. Zoites occurred around the haemolymph sinuses and the digestive diverticulae at all intensities of infection; occurrence in the sub-epithelium, Leydig tissue and gills ...

Return of the native: Survival, growth and condition of European oysters reintroduced to German offshore waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 11, Page 2180-2190, November 2020., 2020
Abstract The European oyster (Ostrea edulis) is under significant threat across its natural distribution range and even functionally extinct in some regions, such as in the German North Sea. Due to its ecological significance in terms of biodiversity and other ecosystem services, the species, and the habitat it provides, are defined as highly ...

Role of microRNAs in the immunity process of the flat oyster Ostrea edulis against bonamiosis

Infection, Genetics and Evolution, 2014
MicroRNAs (miRNAs) are small (∼22nt) non-coding regulatory single strand RNA molecules that reduce stability and/or translation of sequence-complementary target. miRNAs are a key component of gene regulatory networks and have been involved in a wide variety of biological processes, such as signal transduction, cell proliferation and apoptosis.

Forty questions of importance to the policy and practice of native oyster reef restoration in Europe

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 11, Page 2038-2049, November 2020., 2020
Abstract Oyster reefs are among the most threatened marine habitats globally. In Europe, oyster reefs have been extirpated from most locations within their historical range. Active restoration of the native oyster (Ostrea edulis) in Europe has grown substantially in recent years.

Long-term affected flat oyster (Ostrea edulis) haemocytes show differential gene expression profiles from naïve oysters in response to Bonamia ostreae [PDF]

, 2018
European flat oyster (Ostrea edulis) production has suffered a severe decline due to bonamiosis. The responsible parasite enters in oyster haemocytes, causing an acute inflammatory response frequently leading to death.

Investigation of the water environmental DNA/RNA profile for non‐invasive biomonitoring of the fish pathogen Aeromonas salmonicida subsp. salmonicida and detection of immune responses in rainbow trout (Oncorhynchus mykiss)

Environmental DNA, Volume 6, Issue 4, July–August 2024.
Environmental DNA and RNA was used to detect a fish pathogen from water samples. The pathogen could be detected days before fish showed clinical signs of disease and mortality. Abstract Aquaculture industries face challenges in fish production, primarily due to disease occurrence.

Achieving conservation and restoration outcomes through ecologically beneficial aquaculture

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract A range of conservation and restoration tools are needed to safeguard the structure and function of aquatic ecosystems. Aquaculture, the culturing of aquatic organisms, often contributes to the numerous stressors that aquatic ecosystems face, yet some aquaculture activities can also deliver ecological benefits.

QTL mapping for resistance to bonamiosis in the European flat oyster Ostrea edulis [PDF]

, 2008
A breeding programme has been undertaken by Ifremer to produce selected Ostrea edulis families which are resistant to Bonamia ostreae, a parasite which is the most significant constraint on aquaculture of this oyster. Using such families, we aimed to identify Quantitative Trait Loci (QTLs) of resistance/susceptibility to bonamiosis.

Quantification of genes expressed during an in vitro infection of haemocytes from Ostrea edulis with parasites Bonamia ostreae by Real times PCR

, 2008
Oyster fanning represents a significant economic part of the French aquaculture production. This production is approximately about 150 000 tons of shells a year [Buestel, 2004].
